In the first 6 months of life, the young infant has a relatively high zinc requirement to support the very rapid growth of early infancy and growth retarding continues to be highly prevalent among children in low-Income countries. In this study we evaluated the effect of zinc supplementation on the infant growth and development. Materials and methods: In a randomized double blind controlled field trial, 500 lactating women were identified and enrolled into the study within 2 week of delivery. They were enrolled only if they intended to exclusively breast feed for 6 to 12 months. Height (Ht), head circumference HC, weight and development milestone were evaluated monthly to 12 months. Data were analyzed using spss 10 software. Results: WT. HT. and HC in infants of trial group were significantly higher than control group (p M3 ER -
